As the Title suggests, who here in Australia offers a replacement Bolt Handle and Tactical knob for the CZ 452's, 453's and 527's? I've heard of Sterk Shooting and have sent him a message, does anyone else does it? have any of you bought from these guys?thanks

Depending on if you are looking at form or function, you could consider a rubber slip on bolt knob. They don't look great but are a great improvement over the function of the existing knob especially in cold or wet conditions.
